Specification

Interchangeable Hubs
Conduit hubs are available for
Type 3R, 12 and 4/4X applications.
30-200A Type 3R Switches are
provided with a conduit hub provision
and a removable hub plate on their top
rainsheds.

Type 3R ➀
Compression Lug
Neutral Barrier Kit
All Heavy Duty Switches are field con-
vertible for crimp type lugs. When
compression lugs are required for 30-
100A switches, a neutral barrier kit is
required for 1-Phase, 3W or 3-Phase,
4W applications. When compression
lugs are required on 400-1200A
switches, lug mounting kits are
required.
Lugs
30-100A Switches are suitable
for use with 60ºC or 75ºC wire.
100-1200A are suitable for use
with 75ºC rated wire.

Multiple Padlock Accessory
A tamperproof device to provide for
multiple padlocking to meet OSHA or
plant requirements. Accepts up to six
padlocks. Catalog number SL0420.
Standard Carton-12.
Kirk-Key Interlocks
Kirk-Key Interlocks are factory installed
only on Type VII Heavy Duty and Double

unauthorized operation. The interlock
system is a simple method of applying
key interlocks to safety switches so as to
require operation in a predetermined
sequence.
Before consulting the factory, the
following information is required:
• User name and address
• Key number from lock assemblies
on any existing locks to be inter-
